It could be or not :)...
They can also have morning sickess when false pregnant.
I was told in false pregnancy symptoms often start earlier than in real pregnancy but I don't know if this is true.
With my girl it was true, she was "text book pregnant" and was showing all symptoms, so much I really thought they had missed something in the scan!
She even had clear discharge when the puppies would have been due!
She did not previously suffer from strong false pregnancies either so I was really thinking there must be something there to cause her symptoms - There was not.
Good luck for the scan :)
